摘　　要：在强抽运条件下建立了光折变双相位共轭镜光学谐振腔的稳态强度公式,研究了输出功率同两个相位共轭镜的抽运功率之比的关系.调节该比值可使光腔两端各自的和总的输出功率分别达到最大.用Ce:LiNbO_(?),单晶和He-Ne激光构成了光折变双相位共轭镜光学谐振腔.实验值与理论值基本符合.The intensity formulas about a photorefractive resonator formed by two phase-conjugate mirrors (PCM) are obtained under strong pumping condition in steady state. The relation between output power and the ratio of one PCM's pumping beam to another PCM's is studied. Output powers transmitted from the two PCM's and the resonator's total output power can reach a maximum value by changing the ratio, respectively. A photorefractive resonator formed by two PCM's is made by Ce: LiNbO3 single crystal and He-Ne laser beam. The experimental results are in accord with the theoretical ones.
